Jenny Craig BMI Formula and Scale

In fast moving and complicated times, it’s easy to get caught up in the rush and swayed by hype. There’s no shortage of advice available and the number of self-appointed experts of all persuasions appears to double almost on a weekly basis. Diet and weight loss isn’t immune from the trend, with new approaches popping up all over the place. Sometimes it pays to keep things simple, such as Jenny Craig programs that incorporate progressive science alongside traditional strategies such as the Jenny Craig BMI formula and scale.

What is the BMI scale?

BMI, or Body Mass Index, has been in vogue with dietitians and medical practitioners since 1972, when a paper published in the Journal of Chronic Diseases expanded on theories previously disclosed 140 years earlier by Adolphe Quetelet, a Belgian mathematician and statistician. The BMI scale is a measurement tool for quantifying body fat that can be safely removed by dieting. The scale takes both height and weight into consideration, providing a guideline for women and men of all shapes and sizes.

Your personal BMI score is easy to access using the Jenny Craig BMI calculator. Simply input your height and weight and you will receive results that can be viewed in table, graph or chart form for ready access. BMI is categorised into several easy to identify groups, enabling dieters to understand their present weight status and potential for improvement. Your BMI score will fall into one of the following categories.

  • 18.4 or less (underweight)
  • 18.5 – 24.9 (healthy weight)
  • 25.0 – 29.9 (overweight)
  • 30.0 or more (obese)

Jenny Craig Consultants take BMI into consideration when tailoring your personalised weight loss program. Other factors such as age, gender, physical activities and overall health are also investigated in consultation with experienced dieticians and nutritionists. Your meal plan can then be set in motion, and the best part is you get to choose exactly what you want to eat from more than 65 delicious menu selections. All meals are exactingly calorie and portion controlled and prepared by professional chefs just for you.

What is a healthy BMI range?

The benefit of achieving a healthy BMI range can’t be understated. It’s well known that weight is a significant contributor to a range of dangerous ailments and reversing weight gain results in greatly improved health. Underweight people are no less prone to illnesses and ailments that can be dramatically improved by nutritious Jenny Craig meals designed to replenish and revitalise the body. We all make inappropriate lifestyle choices from time to time but it’s easier than you think to return to a BMI healthy weight score between 18.5 – 24.9.

Although Jenny Craig is best known for amazing meals for breakfast, lunch, dinner and snacks, the overall service is far more comprehensive. We also offer lifestyle guidance for promoting wellbeing while replacing unwanted fat with toned muscle. Your personal Jenny Craig Consultant will oversee your program that includes:

  • A healthy relationship with food that includes sensible eating habits, portion control and mindful eating.
  • An active lifestyle where physical activities are gradually increased through natural, planned and playful activities.
  • A balanced approach to living using self-efficacy modelling for creation of a balanced and positive mindset.

What is an overweight BMI range?

People who consider themselves in good shape are often surprised to find they fall into the overweight BMI range. The BMI formula and scale can seem unforgiving, although allowance needs to be made for every individual’s personal weight status. For example, muscular people may receive an overweight BMI score as the calculations measure body mass without discriminating between muscle and fat. Therefore, BMI is mostly applicable for people whose excess weight is mostly fat that can be easily removed by a Jenny Craig weight loss program. An overweight BMI range of 25.0 – 29.9 needn’t be the end of the story; It’s just a guideline to use for weight loss inspiration.

What is an underweight BMI range?

It’s well known that losing weight can help minimise the risk of serious diseases such as heart disease, diabetes and arthritis. The other end of the spectrum is no less fraught with danger and underweight people are also at risk of severe health issues. An underweight BMI of 18.4 or less can indicate potential for a weakened immune system, osteoporosis, anaemia and other serious ailments. Fortunately, nutritionally surcharged Jenny Craig meals are equally beneficial for underweight people who are ready to change for the better.
